CGRPORATIOD APPARATUS FOR S GRING TAPE,

Application filed September 2 To all whom it may concern:

lie it; known that 1, CHARLES ll 'uineimuf, a citizen of the United lfl'ttltfi. residing at Chelsea, in the county of mean and State atMassachusetts, have llN'tltlttlnew and useful linprm'ements in.Qtpparat'us Scoring Tape, of which the following i specification.

My invention relates (0 an improvement in machines for senring orcutting tape 01' strips of paper tiher or similar material for thepurpose of weakening the tape or strips at" intervals.

My improvement consists first in limiting a knit'e in the peripheryof aroll SL1 that its edgedies obliquely to a plane perpendieular to theaxis el the roll, secondly in ya-o'vi-tling knive of such shape thatthey will leave portions of the tape or strips of mateiial. nealheaehedge intact and uncut, andthirtlly in providing a means fan the easy andready imert inn. removal and adjuatuient of said lmi Y0". l

The machine is then started. The gear 3'? and the, roll16 are positively driven and the, gear 37 causes the gear 38 and alsoroll 1a to revolve in the 0pposile dirertion. This causes the lape tomore helween the rolls 15 and 16 and to he aeored at intervals by knives21 and to unwind from the spool 12 The spool QT being 'posilirelr drivencauses the scored lzipo lo wind up on it as" l'asl as it passes betweenthe rolls. This operaiion is eonlinned until the spool 12 i empl y andthe spool 2? hill. The spools are then removed and the operalion hegnnorer again will; new spools.

The purpose for which the tape i ent or seered is to weaken it atintervals: so that it, will separele when a given ainonni' of lension isexerted upon il.
